Abstract
The present invention relates to a system and method for the automated inspection of geometric parameters of railway wheels rolling on a track by artificial vision techniques. The present invention uses a structured light source () that illuminates a line of light () upon a fraction of the surface of revolution () of a wheel (), a CCD camera (), which captures an image () of the illuminated area, and a data processing system that records, digitalizes, geometrically corrects and reconstructs information of the surface of revolution () that is not recorded in the image (), in order to obtain a numeric description of the complete transverse section of the wheel () represented by a reconstructed profilogram () for calculating the geometric parameters of the wheel ().
